Mercedes-Benz AMG GT Service Guide

No automaker can claim that they made the first automobile as we know it today other than Mercedes-Benz. Dating all the way back to 1886, the first patented automobile was produced by Karl Benz. Since then, the German marque has been creating vehicles known worldwide for their quality and prestige. Although they primarily produce luxury sedans and SUVs, they have a strong history of creating world-class sports cars, with the most famous being the 300 SL “Gullwing” in 1954. Their current halo sports car is the AMG GT. The Mercedes-AMG GT Service Guide will be a useful reference guide for owners looking to maintain and properly servicing their AMG GT.

The Mercedes-AMG GT is a joint collaboration between parent company Mercedes-Benz and their in-house high-performance tuning arm AMG. It is the second vehicle from this collaboration, with the first being the SLS AMG. It was developed using knowledge gained from their successful Formula 1 motorsports campaign. There are many variants of the AMG GT, however they all follow the same maintenance schedule. The Mercedes-AMG GT Service Guide will include recommended maintenance and service intervals to prolong the life of the vehicle.

Engine, Oil, Transmission, Clutch

All variants of the Mercedes-AMG GT use the same M178 4.0L Bi-Turbo V8 engine, albeit with different states of tune. The engine is a “Hot-V” set-up, with the turbochargers located in-between the cylinder banks of the V8. This results in better throttle response and packaging. It also uses a 7-speed dual-clutch transmission, with a rear transaxle layout.

The Mercedes-AMG GT Service Guide recommends this maintenance interval schedule:

AMG GT Service A (Every 10,000 Miles)

Check all lights, warning lights and horn operation

Change synthetic engine oil and filter

Replace dust filter (if applicable)

Replace remote key battery

Inspect poly V-belts

Inspect major components for leaks / damages

Check cooling system strength and adjust level if necessary

Check brake fluid level

Check brake pad thickness (front and rear)

Inspect suspension and steering components

Inspect tire condition and set pressures

Check wipers, washer jets and headlamp cleaning system

AMG GT Service B (Every 20,000 Miles)

Check all lights, warning lights and horn operation

Change synthetic engine oil and filter

Replace dust filter (if applicable)

Replace remote key battery

Check cooling system strength and adjust level if necessary

Check brake fluid level

Check brake pad thickness (front and rear)

Check brake disc thickness (front and rear)

Check wipers, washer jets and headlamp cleaning system

Check engine air filter and replace if necessary

Check seatbelts and anchor system

Replace Cabin Air filter

Check and correct headlamp settings

Inspect tire condition and set pressures

Clean water cowling to ensure proper drainage

In addition to these regular maintenance intervals, oil & filter changes should be done every 5,000 miles. Every 4 years or 40,000 miles, the engine air filter and transmission fluid should be changed. Every 5 years or 50,000 miles, all spark plugs must be changed. Finally, every 12 years or 120,000 miles, the fuel filter and coolant must be changed.

Note that the Mercedes-AMG GT Service guide is recommending these if driven regularly on public roads. If the vehicle is tracked, wear and tear will be accelerated and should be serviced earlier and more frequently than the schedule outlined above.

Brakes, Rotors, Pads, Fluid

The high-performance nature of the Mercedes-AMG GT warrants some serious braking capability. Steel brakes are standard on most of the AMG GT line-up, with carbon-ceramic composite brakes being an optional extra (With the exception of the AMG GT-R, which comes with carbon-ceramic brakes as standard). Depending on the driving conditions and driving style, brake wear will vary between vehicles. This is why it is important to inspect the brake wear at each service interval. Brake fluid must be changed every 2 years to ensure that the system isn’t contaminated with moisture, air, or dirt.

The standard steel brakes are 360 mm front and rear. The optional carbon-ceramic brakes are larger with 391 mm up front and 361 mm in the rear. The benefit of carbon-ceramic brakes is that they are lighter, removing excess unsprung mass and they generally tend to last much longer than their steel counterparts.

Tires, Suspension & Alignment

Tires are also wearable items that need to be checked at every service interval. Unfortunately, many owners tend to ignore their tires. As they are the only part of your vehicle that are in contact with the ground, they affect handling, acceleration, braking, and crucially, safety. Wear will vary depending on driving conditions, driving style, and whether or not the vehicle is all-wheel drive or not.

The Mercedes-AMG GT comes with these tire sizes:

AMG GT (Base, S, C) :

FRONT: P265/35/ZR19

REAR: P305/35/ZR19

AMG GT-R

FRONT: P275/35/YR19

REAR: P325/30/YR20

GI Automotive carries a wide selection of road and track Mercedes-AMG GT tires on stock and available to order. A consultation is available to determine which tire is best for your individual driving needs.

Alignment can seriously affect both tire wear as well as the handling characteristics of a car. Therefore, it is imperative that the alignment is checked on a regular basis. The Mercedes-AMG GT Guide recommends checking camber, castor, and toe for tolerances within factory specification, or a custom specification if deemed necessary.

The suspension’s job is to not only keep a comfortable ride; it is also to provide optimal handling characteristics. Properly functioning suspension will keep alignment within specification in a straight line as well as in the corners. Moreover, this keeps the tires from wearing unevenly. At each service interval, it is recommended to check the suspension components for any squeaks, rattles, leakage, or play.
